- the reference numeral 10 generally indicates a portion of a spoolable well completion system and generally includes a metal coiled tubing 12 having one or more signal transmitting passageways such as hydraulic control conduits, passageways, or lines 14 and 14a (Fig. 2) for hydraulically controlling one or more well tools positioned in the coiled tubing, such as a hydraulically actuated well tool 16.
- the hydraulically actuated well tool 16 may be any suitable well tool, such as Cameo Model CTSP hydraulically actuated well safety valve.
- the coiled tubing 12 includes a wall 15 having an inner wall 17, an outer wall 19, and a coaxial bore 13 therethrough.
- the completion system 10 may include various other types of well tools, such as sliding sleeves, gas lift valves, and other tools (not shown).
- the coiled tubing 12 may be any suitable metal such as high carbon steel.
- the metal coiled tubing 12 has the advantages over composite type cables of (1) withstanding higher burst and collapse pressures to which the tubing is subject, (2) greater tensile strength, and (3) allowing greater pressure to be provided in the signal transmitting passageway.
- the hydraulic signal passageway 14 is utilized to provide hydraulic control fluid to the well safety valve 16 for opening and closing the safety valve.
- the second hydraulic signal passageway 14a (Fig. 2) may be run longitudinally downwardly within the wall 15 and through the coiled tubing 12 to operate other types of well tools (not shown).

A single groove 30 or an additional groove 30a, providing one passageway or two passageways, may be provided in the edges 24 and 26, respectively.
- the plate 20 is then rolled in the form of a circle around its longitudinal axis, and, as best seen in Fig. 2, a longitudinal weld 28 is used to weld the edges 24 and 26 together.
- the weld 28 provides a barrier between the grooves 30 and 30a thereby forming passageways 14 and 14a.
- the lengths of the passageways 14 and 14a may be of any desired length and may be different from each other as required for the particular well completion system 10.
- the top of the passageways 14 and 14a thus extend into a wellhead (not shown) for supplying the desired hydraulic control fluid to the passageways 14 and 14a.

- a signal transmitting passageway 14b is formed between the inner wall 17b and the outer wall 19b of a coiled tubing 12b by cutting a portion of the outer wall 19b longitudinally out of the exterior of the coiled tubing 12b.
- the passageway 14b is then formed by placing a closure plate 50 therein such as by welds 52 extending along the edges of the closure plate 50. While, of course, the passageway 14b may be left empty for conducting hydraulic fluid therethrough other types of signal transmitting means may be inserted in the passageway 14b, such as means 54 in which the signal transmitting elements 56 may be fiber optic cables or multiple strands of electrical wire.
- a closure plate 50c is welded into the outer wall 19c of a coiled tubing 12c enclosing a fiber optic bundle 58.
- a closure plate 50d encloses a plurality of passageways 14d which are separated from each other by protective ribs 60.
- Various types of signal transmitting means 58d may be provided in the individual passageways 14d, such as single electrical wires or fiber optic lines.
- the signal transmitting passageways 14e are positioned against the outer wall 19e of the coiled tubing 12e and extend from the outer wall 19e inwardly.
- a protective rib 60e is provided between adjacent passageways 14e for protecting the signal transmitting means 58e.
- the transmitting means 58e are preferably enclosed by a suitable rubber filler 62 which is bonded and holds the transmitting means 58e in place in the passages 14e by being bonded therein.
- a signal transmitting passageway 14f extends from the outer wall 19f towards the inner wall 17f of the coiled tubing 12f.
- the cross- sectional area 64 at the outer wall 19f is less than other cross-sectional areas of the passageway 14f whereby the signal transmitting means 58f may be held in the passageway 14f.
- the signal transmitting means 58f may include any suitable signal means, such as electrical lines or fiber optic lines which are covered by a plastic cover 68.
- the shape of the passageway 14f allows the signal transmitting means 58f to be inexpensively snapped into place in the passageway 14f and securely held therein.
- a spoolable well completion system lOg is shown having a coiled tubing 12g, a hydraulic signal transmitting passageway conduit or line 70 for supplying hydraulic fluid to a hydraulically actuated well tool, such as safety valve 16g.
- the signal transmitting passageway 70 is a concentric annulus which is provided between the inside diameter of wall 17g of the coiled tubing 12g and the outside diameter 72 of a tubular member 74 which is concentrically positioned inside of the coiled tubing 12g.
- the concentric annulus hydraulic signal passageway 70 meets the desired criteria of not being outside of the wall 15g and not interfering with the coaxial passage of well tools through the bore 13g which is in communication with the bore 76 of the well tool 16g.
- a coiled tubing 12h is provided having a slightly reduced internal diameter 17h which provides for an open bore 13h therethrough.
- one or more hydraulic signal transmitting passageways, conduits or lines 80 and 80a are helically wound around the outside diameter 19h of the coiled tubing 12h. The circular wrapping of the hydraulic passageways 80 and 82 provides added strength to the structure.
- the circular wrapped controlled lines 80 and 82 are then encapsulated with an outer cover 84 made out of a suitable strength providing plastic cover made of any suitable material, such as PEEK fiber composite or Ryton "PPS" (polyphenylene sulfide), long fiber reinforced composite, the cover 84 provides a smooth exterior with a non-upset circumference which will readily pass through an injector in a wellhead and at the same time will protect the control lines 80 and 82 from damage while also providing the necessary strength for gripping by hanging means for supporting the coiled tubing 12h.
- a suitable strength providing plastic cover made of any suitable material such as PEEK fiber composite or Ryton "PPS" (polyphenylene sulfide), long fiber reinforced composite
- the pressure capacity of the passageway is inversely proportional to its tangential width while coiled tubing integrity is inversely proportional to the radial height of the passageway.
- the size of the passageway is dependent upon its height and width. Therefore, referring to Fig. 14, the preferred embodiment of the cross-sectional shape of the passageway 14i is oval-shaped with a major axis 90 and a minor axis 92 with the minor axis 92 extending radially and the major axis 90 extending tangentially.
- the oval-shaped passageway 14i which is preferably elliptical-shaped, can be widened out to width w, as compared to a circular passageway, into the low stress region so that the maximum area can be obtained with a minimum passage height h. Therefore, the oval design can be used which optimizes the pressure capacity of the passageway 14i maximizes its size, and minimizes its impact on the metal coiled tubing 12i.
- the oval or elliptical shape provides a stronger design than a round passageway of equivalent area.
- an optimized elliptical passageway 14i can be provided with sufficient area that will withstand high pressure applications while having little to no impact on the burst and collapsed pressures of the tubing 12i itself.
- an elliptical passageway 14i in a 2-3/8 OD x .190 inch wall metal coiled tubing having a width w of 0.080 inches and a height h of .040 inches has a pressure capacity in excess of 15,000 psi while having no observable impact on published collapse and burst pressures for the tubing 12i.
- the ellipse passageway 14i is advantageous for all types of signals being transmitted therethrough, it is additionally advantageous in the case of hydraulic fluid control as it has flow characteristics that would provide downhole well tool operations such as safety valves with comparable closing times to those of a standard control line operated safety valve. In the example shown in Fig.
- the outside diameter D of the coiled tubing 12i is 2.375 inches and the thickness t of the wall 15i is .156 inches and the distance D from the outside 14a of the centroid of the ellipse is t/2.
- the area of the passageway 14a is 2.513 x 10 3 .
- the length of the major axis 90 is twice the length of the minor axis 92. It is preferable that this ratio be substantially no greater than two in order to optimize the area while still withstanding high pressure applications.
